The check valve in the oil filter should keep it mostly full of oil. quality oil filters tend to do a better job of this. (OEM Toyota) 
I have replaced oil filters that felt really heavy due to incorrect change interval. The filter will start to bypass (no longer filter the oil)  once it becomes plugged/ restricted. 

When you see the cheap "paper" media Fram uses verses the Napa or the Wix you'll understand. The latter two won't collapse and block and by-pass your filter. You don't even know this is happening. so you are just blindly happy with a lower grade product. Just sayin' from years of mechanic experience and viewing engine failures.   

Here's my worthless opinion... if I take my new rebuilt 22RE and blocked of the oil port and oil filter boss on the side of the block, so no oil filter, and drive my truck with no oil filter for 5,000 (my oil change interval), then changed the oil, I'd wager a 6-pack of your favorite libation that there will be zero to neglible measurable wear on any crankcase oil lubricated parts.
